Most definitely. Rose coloured glasses to the nth. You can now make your spouse look 20 years younger in a flash. Beer goggles to the nth. She'd use it on me too, no doubt. "Here's how I'd like you to look, honey dear, now off to the plastic surgeon to trim some fat and nip and tuck some of that flab and fix that nose you hate but I actually like, but you hate so much for some reason, so you can be happy at last and forever. I'm being sarcastic if you didn't detect it. Nothing lasts forever. You'll need another upgrade eventually."

@Richard.Hein:So what you are saying is that with Minecraft and Hololens (+ 3d printer) I could mine bitcoins then print them out and spend them down the shops?

Indeed you could do that if you wanted to - a guy out there made some 3D printed Bitcoins already, and yeah you can make it what would be like a paper wallet is - in Bitcoin a wallet is a program that allows you to create and manage addresses which a user sends and receives Bitcoins. You can print off a paper wallet and thus Bitcoin works offline and in that case is most like a common paper bill with an address instead of a serial number. It's a bit more complicated because of digital signatures and pgp encryption.

Many, many new business ideas and uses are being dreamed up daily right now, because Bitcoin is a protocol that allows all kinds of programmable money ideas that no one has even thought of because it's so new. With holograms, one must still have some skill and artistry to make something someone would buy, and that art itself can be used to form digital signatures and have value as a type of sidechain linked to Bitcoin (the currency), as physical property which people buy, sell and trade for other such goods and services. But I digress.

Thanks for the link, btw. I like the design a lot. It looks a lot like a fancy pair of ski goggles. Considering all the hardware in there and it being untethered entirely, it's a lot in a small and elegant package.

The HoloLens explains fully why Microsoft wanted Mojang and Minecraft so badly, and why it's so valuable. With the HoloLens, Minecraft becomes a simple yet powerful modelling tool, and already has a huge ecosystem and existing models to share and explore. People can build Turing complete machines in Minecraft and mine actual Bitcoin that has been programmed into mods as part of the game (although they are not Bitcoin miners in the "real" sense, as the game has been seeded with Bitcoin that already has been mined - I say this just to avoid confusing some people, as I am not claiming that Minecraft allows you to mine Bitcoin, but one could model the SHA256 hash function with Minecraft for fun and zero profit, or make rare blocks that have some Satoshi reward when mined). You can also already print 3D models of Minecraft models. Minecraft + HoloLens is worth a billion at least.

Apply Pay vs. Bitcoin = Apple loses, IMNSHO. The Canadian government, through the Royal Canadian Mint was working on a digital currency and hardware, MintChip, but has given up on it and is actually trying to sell off some of the technology. I think this is a huge victory for Bitcoin and decentralization, since even a government which could easily make it legal tender for paying taxes has given up on making a centralized electronic currency. Now if Apple Pay tried to integrate with Bitcoin, using Sidechains or another similar method, it has a chance, but they probably won't integrate Apple Pay with Bitcoin, because it is Apple and Apple has a problem with giving things away, they are into too much centralization, and it has obviously worked for them in the past. I don't think it will work for much longer, however. Once the decentralized industrial complex grows to sufficient size, via 3D printing and other additive manufacturing devices spread, people can print off smartphones and computers like the HoloLens whenever they want, sharing data and ordering increasingly "raw" matter, then we will well and truly be a knowledge based economy. So it might work for a while longer, but long term I think Apple Pay is doomed, but Bitcoin can provide the foundation for a knowledge based economy using proof-of-work schemes and has all the advantages but none of the disadvantages of Apple Pay.

Here we show that self-propulsion in quantum vacuum may be achieved by rotating or aggregating magneto-electric nano-particles. The back-action follows from changes in momentum of electro-magnetic zero-point fluctuations, generated in magneto-electric materials. This effect may provide new tools for investigation of the quantum nature of our world. It might also serve in the future as a "quantum wheel" to correct satellite orientation in space.

@androidi: I've been pondering the safety aspect as well. One can make walls of this around someone where the waves are cancelled out where the body is, creating a kind of space all around the body, and a kind of suit like a swarm of bees around the body, but the ultrasonic waves never touch the body. However, using ultrasound to also detect tumours in the body and even focusing ultrasonic sasers into the body to destroy cancer cells is within the realm of possibility.

By the way, very new research in neuroscience shows that sound waves propagate and back propagate along neural axons and dendrites and over the surface of neurons and provides yet another dimension to consciousness to explore.

This is the year of acoustics and the beginning of a new era in computing. HoloLens is awesome and to overlay Pixie Dust with holographic projection would enable an endless number of applications that we haven't dreamed up yet.
